HYDRO-DEMOLITION SERVICES FOR CONCRETE REMOVALS
Our Company specializes in the rehabilitation of the following types reinforced concrete structures:
We understand what is important to concrete repair contractors. Bridge deck repair is necessary to keep our nation’s roadway system in service. We have developed the Fast Track Selective Hydro-Demolition Bridge Deck Overlay Method, which is used by many Highway Departments and Contractors, as the fastest and longest maintenance free construction method to repair and preserve bridge decks. The service life of bridge decks are extended by 25-30 years when this method is used with minimum disruption to traffic.
The major #1 risk to an owner when putting out a bid for a bridge deck preservation or rehabilitation project are variable quantities.
Variable quantities cause all sorts of problems such as:
a. Uncontrollable costs.
b. Extended time of completion.
c. More money required to complete.
d. Change orders.
f. Contractors not bidding apples to apples.
g. Unbalancing of bids, etc.
Basically performing work totally out of control in terms of problems and money.
The benefit to owner or consultants using Fast Track Selective Hydro-Demolition is the ability to eliminate or reduce variable quantities.

NOTE: There is no such thing as pour ready when using Deep Hydro-demolition. As soon as the surface dries there is a concrete dust, which can be a bond breaker. After Deep Hydro-demolition, the surface must be sandblasted or water blasted with 7,500 PSI capability to remove all laitance before the new concrete overlay is installed.
